Many do. But that's why I'd rather just learn new skills and do stuff myself if I'm going to have to check people's work and fix it anyway.
But... There are many good people out there. Unfortunately, they're hard to find in the cesspool. I see this shit at work too. No industry is immune.
I don't accept that we just have to be hopeless though. I like to think that I'm a role model for younger practitioners at work for speaking up and not accepting bullshit excuses for mediocrity. I've produced some good people from training. Generally, there's something already in them that makes them receptive though. I've had shit bags where I had to recommend firing because they'll likely kill someone. I don't know how to fix it all. You probably cant. Ending fiat and ridiculous regulation would help a lot though
